“Shared Count” is not my company. While we can leverage their API to reduce queries per page, you can also use the “Native” query to get the counts directly from Facebook, Pinterest, etc and not use their paid service.
When we launched the Shared Counts plugin, “Shared Count” had a generous free plan so we added an integration with it. They have since reduced the free plan to make it not viable for most users, so we recommend using the “Native” count if you need counts.
If you just need sharing buttons and don’t care about the total share count, select “None” as the source. Personally, I no longer include counts in the social sharing buttons on sites I build because they don’t add much value, the native counts fail sometimes, and it’s not worth paying “Shared Count” for access to the data.
